Application filed June 20, 1912. Serial No. 704,822.

To all whom it may concern:

Be it known that I, RUooLr Koimnn, a subject of the Emperor ofAustria-Hungary, residing at Niederlossnitz, near Dresden, in theKingdom of Saxony, Germany, have invented certain new and usefulImprovements in Apparatus for Decanting or Settling Liquids, of whichthe following is a specification.

The invention is of special importance for example in its application topaper mills. The water flowing oif from a paper-making machinecontainsnumerous fibrous particles, which float about in the water and flow oiltherewith.

Now the object of the apparatus according to the present invention is torecover these fibrous particles from the efiluent water, so that theycan again be returned to the paper-making machlne and thus escape beinglost.

In the accompanying drawings the new apparatus is fully illustrated;Figure 1 being a side elevation partly in section, of the invention, andFig. 2, being a plan view of the same, also partly in section.

The funnel a is shown in this construction as made of sheet metal but,if necessary, the said funnel a could also bemade' of masonrywork. Inthe upper part of the funnel a there is built in an invertedfrusto-oonical member I; which has no spout or point. In the upperportion of the funnel b there is a roof-shaped cover 0. The lower edgeof the funnel b is also provided with an annular edge 03 that is turnedupward, a similar edge e also being provided in the roof-shaped cover a.I

The water is supplied through pipe f into the center of the apparatusand runs down on the roof-shaped surface a over the upper edge of acylindrical container g. The principal objects of the arts 9, c, e areto cause the water to be uni ormly distributed in all directions andmade to flow over theedge 6 without any eddying movements.

Running completely around the entire apparatus is a groove or channel Itto the periphery of which the overflow chute c' is attached. Theoverflow chute i and the chute h are destined to conduct the purifiedwater to the proper outlet or outlets.

A scum formation takes place on the surface of the water around aboutthe edge e and, in order to remove this, there is provided a shortintermediate chute n with a valve 0. This valve 0 is normally keptclosed but, if a large quantity of scum has collected, then the saidvalve 0 is opened for a short space of time so as to allow the scum toescape at n and z. r

At the lowest point-of the funnel a there Is an escape pipe m which isOnly opened when it is required to subject the whole apparatus to athorough cleaning.

The object of the pipe is is to carry oit the fibrous particlesseparated from the water and return them to the paper-making machinery.

The water arrives fromall sides between the edge e and the funnel b witha, slow steady movement in the downward direction shown by the arrowsand is thus guided in the funnel 6 toward the middle. As the water flowsoff at the top throu h h, the movement is consequently boun to takeplace in an outward arc-shaped direction around the edge d. In order tounderstand the operation of my apparatus properly, it must be pointedout that the speed of the water is slow in general, but it is notuniform as it flows much more slowly at 6 than at cl. At the topor levelof the edge d the speed is the greatest, and the water will not flowmore slowly again until it attains its minimum at the top or level of h.The centrifugal movement of the water around the edge 03 at the pointwhere the letter a: is inserted in the drawin brings the actualpurificative eflect into p lay as, in this zone, at a: the fibrousparticles are thrown out of the water by the centrifugal force and sinkslowly downward into the deeper zone marked 3/, from which it is removedthrough pipe I: by a suitable What I claim and ters Patent, is:

In apparatus for decanting or settling liquids, a vertical frame, afunnel mounted on said frame, an escape pipe at the lower end of saidfunnel, an inverted frusto-conical member 6, mounted centrally in saidfunnel and extending above it, an upwardly and inwardly inclined li onsaid member I), a roof-shaped member 0, in the upper part of member I)having an upwardly and outump. desire to secure by Letsaid funnel withsaid escape pipe, as herein wardly inclined lip, a supply pipe, ashallow set forth.

receiver into which said pipe discharges, a receiver wider and higherabout said first mentioned receiver, an exterior overflow channel,around the upper edge of said funnel and extending below it, an escapepipe 2', and a chute n, connecting the interior of BUDOLF KORNER. 1,.8.]
